文章利用脉冲对的交叉相位调制（XPM）效应和非线性掺铒光纤放大环镜（ED-NALM）的整形放大作用,提出了一种对无啁啾高斯脉冲进行脉冲压缩的设计方案。数值模拟的结果表明,利用此方案可将脉宽为10 ps、中心波长为1 553 nm的无啁啾高斯脉冲压缩成脉宽为150 fs的无基座超短脉冲,且脉冲得到了很好的放大。

Objective: To study the relationship between serum exosomes long non-coding ribonucleic acid (lncRNA) prostate cancer gene expression marker 1 (PCGEM1), micro ribonucleic acid (miR)-129-5p and clinical pathological characteristics and prognosis of patients with non-small cell lung cancer (NSCLC). Methods: 125 patients with NSCLC who were admitted to Nanjing Brain Hospital from February 2016 to January 2018 were selected as NSCLC group, 70 healthy individuals who were underwent physical examinations were selected as health group during the same period. The venous blood were collected of two groups, and the serum exosomes were extracted. The expression of serum exosomes lncRNA PCGEM1 and miR-129-5p were detected by the real time quantitative polymerase chain reaction (qRT-PCR). The relationship between lncRNA PCGEM1 and miR-129-5p was analysed by Pearson correlation. And the relationship between serum exosomes lncRNA PCGEM1, miR-129-5p and clinical pathological characteristics of patients with NSCLC was analyzed. 5 years followed up for patients with NSCLC, the prognosis was analyzed by plotted Kaplan-Meier curve, the risk factors for poor prognosis were analyzed by multivariate Cox proportional risk regression model, and the predictive value of lncRNA PCGEM1 and miR-129-5p of predicted the NSCLC prognosis was analyzed by the receiver operating characteristic (ROC) curve. Results: The relative expression level of lncRNA PCGEM1 of NSCLC group was higher than that of healthy group, while the relative expression level of miR-129-5p was lower than that of healthy group (P<0.05). The relative expression level of serum exosomes lncRNA PCGEM1 was negatively correlated with the expression of miR-129-5p (r=-0.420, P<0.05). The expression of serum exosomes lncRNA PCGEM1 and miR-129-5p were related to TNM stage, differentiation degree, and lymph node metastasis of patients(P<0.05). The Kplan-Meier survival curve showed that the 5 years survival rate of lncRNA PCGEM1 low expression group was 69.05% higher than 35.53% of lncRNA PCGEM1 high expression group, and the 5 years survival rate of miR-129-5p high expression group was 68.09% higher than 33.80% of miR-129-5p low expression group. Multivariate Cox proportional risk regression showed that TNM stage III, lymph node metastasis, high expression of lncRNA PCGEM1, and low expression of miR-129-5p were independent risk factors for poor prognosis of patients with NSCLC (P<0.05). ROC curve showed that the area under the curve (AUC) of predicted the NSCLC prognosis by the combined detection of lncRNA PCGEM1 and miR-129-5p was 0.865, and the predictive value was higher than both separately predicted. Conclusion: The expression of serum exosomes lncRNA PCGEM1 of patients with NSCLC is upregulated, while the expression of miR-129-5p is downregulated, the expression of both is related to TNM stage, differentiation degree, and lymph node metastasis of patients with NSCLC, and closely related to patient prognosis, which has good predictive value for poor prognosis of NSCLC.

The experiment was to evaluate the effect of fish meal replacement by defatted Hermetia illucens powder on growth performance, feed utilization and body composition of Micropterus salmoides. A total of 240 juvenile fish with an initial body weight of (11.42±0.25) g were randomly divided into four groups with three replicates in each group and 20 juvenile fish in each replicate. The experiment lasted for 6 w. The diet of the control group contained 40% fish meal, and the fish meal of the control group was replaced by 25% (R25), 50% (R50) and 75% (R75) of defatted Hermetia illucens powder, respectively. The protein and fat content of the four diets were 48% and 8% respectively. The results showed that the weight gain rate and feeding rate in R25 group were significantly higher than those in R50 group (P<0.05). The hepatosomatic ratio in R50 and R75 group was significantly higher than that in control group (P<0.05). The content of crude protein, ash and phosphorus in R50 and R75 group were significantly lower than those in control group (P<0.05). The total amounts of lysine, isoleucine, glutamic acid and essential amino acids in R50 and R70 group were significantly higher than those in control group (P<0.05). The content of methionine, leucine, phenylalanine, aspartate and tryptophan in R50 group were significantly higher than those in control group, R25 and R75 group (P<0.05). The cystine content in R25, R50 and R75 group was significantly higher than that in control group (P<0.05). The experiment indicates that 75% fish meal replaced by defatted Hermetia illucens powder didn't affect the growth performance and feed utilization efficiency of Micropterus salmoides, but resulted in liver enlargement of Micropterus salmoides. The body composition was changed for Micropterus salmoides fed with defatted Hermetia illucens powder. [ABSTRACT FROM AUTHOR]
